Hello,

When launching SurfaceFeatureExtract OF2.2.x on redhat6.4 sometimes I get the following error. If I launch the same files and SurfaceFeatureExtract on OF2.2.x installed on Ubuntu no error at all.

Code:

has anyone encountered the same error?

Thank you

OK problem solved.
Cause of the error: the STL file used were seen as non closed manifold (even if graphically no evident holes were present)
Solution: recreate the STL with a better quality mesh.
relaunch surfaceFeatureExtract with the new STL and the problem disappears.
Why then in Ubuntu everything works since the beginning, I have no idea.
